Something strange happened in December 1967 in Australia. Our Prime Minister went for a swim at Cheviot Beach (in the Point Nepean National Park) and never emerged from the bay. I wasn’t born then but I believe there were all sorts of theories as to what happened. These included being murdered because he was opposed to the US Government setting up a nuclear base at Pine Gap or that he had been kidnapped by communists. This was despite an official report that his death was accidental. Apparently the conditions that day were very turbulent but Holt still chose to swim despite being warned not to.
